theodp writes: Fourteen years ago, Microsoft Wallet promised 'secure, convenient purchasing on the Internet.' That was then, this is now. TechCrunch reports that the first commercial for Google Wallet has been unveiled, and it stars Seinfeld’s George Costanza and his overstuffed, exploding wallet. At launch (TBD), Google Wallet will allow you to use a Google Nexus S 4G (from Sprint) to tap-to-pay using Citi MasterCard cards or the Google Prepaid Card. Not to be outdone, PayPal offered a video sneak peek of its upcoming virtual wallet offering, which is promised to be more than 'just shoving a credit card on a phone.' In May, PayPal sued Google over electronic wallet technology, alleging that the search giant hired two of its former execs to obtain trade secrets for a mobile transactions project.
